I'm new to Canada, came through my employer on a closed WP. I'm LMIA exempted ( under International Mobility Program (C63- ICT- Specialized knowledge only- R205(a))) and my employer filed a amendment petition recently to change my role and location which is in progress with IRCC. with this amendment petition, my role and NOC code is changing. however my duties on both NOC codes overlap, in this case which NOC code i should use as my Primary occupation when i submit my express entry profile.
